Abstract

Quality control is applied to almost every procedure during the manufacturing process in industry. However, it is not used commonly in restorative dental practice. The surface contour or shape of the tooth is very irregular, a 'so called' free form surface. Measurement of such a free form surface needs a specified strategy to satisfy the measurement accuracy. This paper attempts to propose an optimal measurement strategy to measure the occlusal molar tooth surface, in order to achieve a degree of measurement and quality control in restorative dental practice.
